Nigeria is the second leg of Li's four-nation Africa tour, which will also take him to Angola and Kenya. Before Nigeria, Li paid a visit to Ethiopia, where he also visited the African Union headquarters and delivered a speech there on China's Africa policy.

Pushing forward the new-pattern industrialization, informationization, urbanization and agricultural modernization, China is transforming its economic development model and structure, which brings more cooperation opportunities for China and Germany, Xi added.

Asia, particularly Northeast Asia, is the source of growth and innovation, and there is a huge, great expectation from the international community that this is an Asian Era, he said.

Xi will also visit the EU headquarters during his tour, becoming the first Chinese head of state to make such a trip since China and the EU established diplomatic ties in 1975.

China's Policy Paper on the EU: Deepen the China-EU Comprehensive Strategic Partnership for Mutual Benefit and Win-win Cooperation is the second of this kind, following the first one issued in November 2003.
